A block of wood is weighed on a beam balance it's mass is 45g the density of the block is 1.8g/cm3 determine the volume of the block
The density of a substance is defined as its mass per unit volume. Therefore, to determine the volume of the block, we can use the formula:
Density = Mass / Volume
In this case, we know the mass of the block is 45g and the density is 1.8g/cm^3. Rearranging the formula, we can solve for the volume:
Volume = Mass / Density
Volume = 45g / 1.8g/cm^3
Using unit cancellation, we can convert grams to cubic centimeters:
Volume = 45g / 1.8g/cm^3 = 25cm^3
Therefore, the volume of the block of wood is 25 cm^3.
To determine the volume of the block, we can use the formula:
Volume = Mass / Density
Given that the mass of the block is 45g and the density is 1.8g/cm³, we can substitute these values into the formula to calculate the volume:
Volume = 45g / 1.8g/cm³
To cancel out the grams in the numerator and denominator, we need to convert grams to cubic centimeters. Since the density is given in grams per cubic centimeter, we don't need to convert it.
So, the volume of the block is:
Volume = 45g / 1.8g/cm³
= 25 cm³
Therefore, the volume of the block is 25 cm³.
An empty container weighs 20g after it is filled with water the container weighs 60g calculate the volume of the water in the container (density of water is 1g/cm3
To calculate the volume of water in the container, we can use the formula:
Volume = Mass / Density
The mass of the water can be determined by subtracting the mass of the empty container from the mass of the filled container:
Mass of water = Mass of filled container - Mass of empty container
= 60g - 20g
= 40g
Given that the density of water is 1g/cm³, we can substitute these values into the formula to calculate the volume of water:
Volume of water = Mass of water / Density of water
= 40g / 1g/cm³
= 40 cm³
Therefore, the volume of water in the container is 40 cm³.
The density of alcohol (liquid)is 0.79g /cm3 and density of ice is 0.9g/cm3
To answer your question, I assume you want to compare the densities of alcohol (liquid) and ice.
The given density of alcohol is 0.79 g/cm³, and the given density of ice is 0.9 g/cm³. Since the density is a measure of mass per unit volume, we can conclude that ice is denser than alcohol.
In other words, if you were to compare equal volumes of alcohol and ice, the ice would weigh more due to its higher density.
To determine the volume of the block, we can use the equation:
Density = Mass / Volume
Given that the mass of the block is 45g and the density is 1.8g/cm^3, we can rearrange the equation to solve for the volume:
Volume = Mass / Density
Substituting the given values:
Volume = 45g / 1.8g/cm^3
Now, we need to ensure that the units are consistent. The density is given in grams per cubic centimeter (g/cm^3), so let's convert the mass to the same units:
Volume = 45g / 1.8g/cm^3 * 1cm^3/cm^3
Simplifying, we cancel out the grams (g) in the numerator and denominator:
Volume = 45 / 1.8 cm^3
Finally, performing the division:
Volume = 25 cm^3
Therefore, the volume of the block of wood is 25 cm^3.
